well i tried reading from page one, but had to stop at the end of two cuz i got tired of reading the stupid shit on flaming imports. Ive had my 1994 TBI S-10 (4x4 even) up to about 93, and i had the speedo buried on my 1995 CPI ZR2 (on mud-terrains, and didnt have a problem). In my Altima (bone stock 2.4L pushing 150 hp and 155 tq, something like that) ive had it to 119, the limiter is set at something like 125, but it wasnt my car at the time so i didnt want to go faster. And anybody who says my car is rice, **** you, cuz its not. rice are the cars with type r stickers, whale tails, and primer gray body kits. my room mate has a GSXR 750 he's had to 168, and he wants to drop a 1000 engine in there. it would be safe to say he would go over 190, with no problems.
